sPHENIX is a new detector at RHIC.

HI Gunther and Dave,

We will put together a few plots about MVTX. 

Cheers,
Ming

Friends,


We were asked last week to present an "sPHENIX update" at this week's BNL 
Science and Technology Steering Committee meeting. The presentation has now 
been confirmed for Friday, July 7, at 9:30AM and will be 30+10min. We 
mentioned on several occasions last week that this would be a good 
opportunity to present new or updated material on the commissioning progress. 
We probably did not stress the importance of this meeting sufficiently - this 
is BNL's most important advisory committee, the talk has been requested by 
the new BNL director and the meeting will be attended by essentially all of 
BNL leadership. The meeting is not open to the public, which affords some 
discretion in the material to be shown, but obviously we want everything to 
be correct.


Could we ask all the subsystem leaders and commissioning experts again to 
consider which plots and event displays could be added to the list of 
approved material to make sure we put our best foot forward and do justice to 
the enormous amount of work that has been done over the last weeks and months 
and...?


>From last week's physics coordination meeting, it seems that a number of new 
>plots should be close to ready
- TPC event display with magnet on, z_vtx in a reasonable location
- ZDC/calo correlation
- an update of the pi0 plot
- first MVTX plots demonstrating data readout (and beam halo)
- INTT possible on the verge of location collision vertex?
- ....


A stretch goal that would leave a big impression would be a HCAL or 
HCAL/EMCAL event display showing a dijet-like collision event. We certainly 
have taken enough data to expect a number of high pT jet events to be among 
the collected data. Having such an event display by the end of this week 
would be much more valuable than having it in a couple of weeks from now.


Any plots that show the beginning of the data reconstruction process (calo 
clusters, topo clusters, track seeds, hit correlations in the silicon 
detectors would be valuable.


Please let us know if you have additional suggestions for material to be 
included. The expert committee will surely understand that we are right at 
the halfway point of our commissioning effort, but we should expect to be 
asked about basic parameters, such as live channels for each subsystem, 
readout rates achieved and total commissioning data collected. Please make 
sure to compile any information along these lines. 


It is certain that we will need support from BNL leadership and this 
committee in the future, let's try to put on a good show.


Best,


Gunther and Dave
